When it rains, it pours, but not when it doesn't

When it rains, it pours, but not when it doesn't

2008 ended with extreme cold weather. 2009 has picked up the baton, but more so in the rain category.

The first 10 days of January in Seattle were the 3rd wettest first 10 days of the year for Sea-Tac Airport. (See, they do have a stat for everything.) It's the 4th if you include the Federal Building records which go back to 1891:

1. 5.98 INCHES 1998
2. 5.49 INCHES 2007
3. 5.44 INCHES 1914  ** FEDERAL BUILDING
4. 5.12 INCHES 2009
5. 5.04 INCHES 1956

Usually, we see 1.70" of rain for the first 10 days of the month.

OK, so quote fulfilled, Mother Nature shut off the spigot.  In the month since -- Jan. 11 to Feb. 10 -- it's been the driest January 11 to February 10th on record. All the way back to the late 1800s:

1. 0.64 INCHES 2009
2. 1.27 INCHES 1994
3. 1.41 INCHES 2007
4. 1.41 INCHES 1917  ** FEDERAL BUILDING
5. 1.46 INCHES 1962

Usually, we'd have 4.99" during this period.

Still researching: What the record is for number of cloudy observations recorded at 2:54 p.m. at Sea-Tac Airport in months that begin with a vowel and have a full moon before the 15th :)
